Foot-operated valve |
摘要 |
A foot-operated valve includes a valve set with a hollow seat and a push rod that extends movably and slidably into the hollow seat and that has a bottom end with a plug provided therearound. The push rod is biased to a first position, wherein the plug blocks normally a distal bottom end of a tubular sleeve that is secured in the hollow seat. When downward pressure is applied on the push rod to move the push rod to a second position, the plug ceases to block the bottom end of the tubular sleeve to permit communication between water outlet and inlet holes of the hollow seat. A control unit is secured to the hollow seat and includes a button retaining seat, a button and a rotary member. The control unit is operable to retain releasably the push rod in a depressed state to maintain communication between the water outlet and inlet holes even when the downward pressure applied on the push rod is extinguished.
